When it comes to protecting coatings, it is essential to strike the right balance between controlling germs in order to avoid economic damage on the one hand and tolerating microbial life where it is necessary and useful on the other. The new book from Frank Sauer provides a comprehensive overview of the working mechanisms and possible applications of microbiocides for coatings - invaluable for formulators and technicians as well as for business people with a basic knowledge of chemistry and biology.

Preface
“Everyone is trying to accomplish something big, not realising
that life is made up of little things.”
Frank Clark (1860 – 1936)
Microbicides are substances that represent two sides of the same coin. On one hand, they help to control microorganisms that are responsible for the deterioration of materials and for causing commercial damage worth billions of euros a year. On the other, they are regarded with suspicion because their action can have side-effects on humans or on the environment or both.
Microorganisms have been part of our biosphere for billions of years, during which time they have been extremely successful due to their ability to adapt to the most challenging of conditions. Human life as we know it would not have been possible without the tireless assistance of these tiny organisms. Our intention must therefore not be to combat germs wherever they are encountered – microbicidal measures should only be taken in situations where germs cause harm to humans, be it out of medical need or the need to protect a material.
This book seeks to provide an overview of the different aspects of material protection, covering the spectrum from basic information about the universe of microorganisms, to the innate properties of microbicides, to the state of the art and finally to legislative aspects. The biggest challenge in this regard has been deciding which of the key issues to select from the vast wealth of information available, without straying off course. It therefore goes without saying that it has not been possible to cover every detail in depth, as that would have substantially exceeded the scope of the book. Wherever appropriate, references are provided so that the reader can conduct further research.
The book also seeks to familiarise laboratory assistants, technicians, graduates, engineers and chemists with the principles of material protection in the field of coatings. However, it should also prove rewarding to business people with a basic knowledge of chemistry and biology.
I would like to thank all those colleagues who provided information on selected topics and proffered their advice and made various suggestions and recommendations.
My very special thanks go to my wife and my daughter for their endless patience during the preparation of this book and for their forbearance when I was so often unavailable for leisure pursuits, especially at the final stage of writing. Without their support, this book would not have been finalised in time. I am also greatly indebted to them for giving a reader’s perspective of the book.
